5 Things Security Pros Need To Know About Machine Learning

#4 Supervised or Unsupervised Learning? It Depends

There are two camps in the machine learning space: those who adhere to supervised learning and those that rely on unsupervised learning. Choosing the one best suited for your organization will depend on your resources and environment, experts say.

With Supervised Learning, analysts help train the system. Unsupervised Learning is autonomous; it uses a set of algorithms and learns from its dataset.

Just as every immune system is different, every network is different, says Justin Fier, director of cyber intelligence with Darktrace, a developer of self-learning software inspired by the biological principles of the immune system, which uses unsupervised machine learning.

Any adversary with the right amount of resources and patience can get through your perimeter. We take the approach -just as your immune systems does - of getting a sense of self, Fier says. Once deployed on a network, the companys Enterprise Immune System constantly learns what is normal for the network. From that, analysts can pull out the most minute anomaly the needle in the haystack of patterns that just dont belong, Fier says.

We do it in an unsupervised way, meaning we are not training the device. As far as learning what the devices are, the pattern of life, the different characteristics of the data we are ingesting for the modeling - all of that is done unsupervised without any human hand at training it.

I wouldnt say one [approach] is better than another, says Fier. It comes down to resources. Once, Fier deployed the technology for a proof-of-value at a company hosting a sporting event. The network administrator was scrabbling. He said he had laid enough fiber cable to go to the moon and back five times, Fier says. He didnt have the time to do a proof-of-value evaluation.

We plugged [the Darktrace tool] in and pointed data to the device and that was it. We didnt have to spend time building up configuration files or telling it what to do. It was already built-in and learns from data, Fier says.

Is one approach better than the other? It depends on the environment you want to deploy in. I would err on the side of doing unsupervised because I dont have to assign a team of people to set the things up and train it on the datasets, he says.
